Once access is granted, connection to ARCC HPC resources may be established via SSH.
Note that SSH connections require Two-Factor Authentication. To connect to Beartooth, please run: ssh <username>@beartooth.uwyo.edu

1. Note: you need to not be connected to the UWguest wireless network.

2. Open a terminal window or similar command line interface (CLI). Learn how.

3. Type in “ssh <username>@<clustername>.arcc.uwyo.edu” and press enter.

   1. For example: ssh <username>@beartooth.arcc.uwyo.edu

      1. The first time you log in you will get a message saying the ‘authenticity of the host … can’t be established' and asking if you ‘are sure you want to continue?’.

      2. Enter ‘yes’.

   2. You will then see a Notice to Users and a Two-factor Authentication message, with your mobile device ready, enter your password and accept the Duo Mobile (2FA) challenge when it pops up.

      1. The Two-factor message may say something about entering your password in this form: <password, token>. This is no longer necessary, but still possible to do.

1. Once you are connected, a bunch of text will scroll by. This will vary depending on the cluster. On Beartooth, for example, there are usage rules, tips, and a summary of your storage utilization across all projects that you are part of.

   1. Note that when you are logged in, the command prompt will look something like this: [your_username@blog3 ~]$

      1. This shows your username and which login node you are currently utilizing. The login node (here, blog3) can, and probably will, change from one session to the next.

      2. The “~” indicates that you are in your home folder on the storage system.

Condo Model

Our Beartooth cluster follows a condominium-style model of resource management. Investors, which are individual researchers or groups of researchers, work with us at ARCC to purchase compute nodes and storage. These resources are then installed in our cluster and administered by the ARCC system administrators.
